Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a multi-hole pipe processing device for drilling holes in pipe fittings. Background Technology

[0002] Chinese Patent Application No. 202121950598.2 discloses a drilling device for processing thin-walled cylindrical parts, which includes a horizontal moving structure, a vertical moving structure, a drilling structure, and a part placement table structure. When the device is in operation, the thin-walled cylindrical part to be drilled is placed on the part placement table structure. The horizontal moving structure drives the drilling structure horizontally above the part, and the vertical moving structure drives the drilling structure vertically to press it against the part, thus drilling the part. This device can only perform single-hole processing on the part, its processing type is limited, and its operability is low, making it unable to meet the needs of multi-hole processing operations. Therefore, improvement is necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-hole pipe fitting processing equipment, which can realize multi-hole processing of pipe fittings, and has the characteristics of fast and efficient processing, as well as high degree of automation control, strong controllability and excellent and stable processing quality.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A multi-hole pipe fitting processing device includes a frame, which includes a frame plate, vertical guide columns, and a lower pressure plate. Two vertical guide columns are symmetrically arranged on the frame plate of the frame. The lower pressure plate is located above the frame plate, and its two ends are movably sleeved on the two vertical guide columns. The lower pressure plate can move up and down along the vertical guide columns above the frame plate. The device is characterized by further including a front hole processing mechanism and a rear hole processing mechanism located near one side of the front hole processing mechanism.

[0006] The front hole machining mechanism includes a front hole cutter and a front hole positioning head. The front hole cutter and the front hole positioning head are arranged correspondingly above and below each other. The front hole cutter is a vertically arranged cylindrical structure located at the lower front of the lower pressure plate. The front hole positioning head is a longitudinally arranged cylindrical structure located at the upper front of the frame plate. The front hole positioning head has a machining front hole that is directly opposite the front hole cutter. When the lower pressure plate is subjected to force and moves downward, the front hole cutter can be inserted into the machining front hole of the front hole positioning head.

[0007] The back hole machining mechanism includes a back hole positioning upper block, a back hole positioning lower block, a movable tool assembly, and a tool reset mechanism. The back hole positioning upper block is located below the lower pressure plate at the front, and its bottom has a longitudinally arranged arc-shaped positioning upper groove. The back hole positioning lower block is located above the frame plate at the front, and its top has a longitudinally arranged arc-shaped positioning lower groove. The arc-shaped positioning upper groove and the arc-shaped positioning lower groove are arranged vertically, and the arc-shaped positioning lower groove contains a vertically arranged machining back hole.

[0008] The movable tool assembly includes a tool mounting block, a cylindrical mounting head, and a rear hole tool. The tool mounting block is vertically movably positioned above the frame plate at the rear of the rear hole positioning lower block, with its bottom moving through the frame plate. The cylindrical mounting head is longitudinally positioned at the front of the tool mounting block. The rear hole tool is a vertically positioned cylindrical structure, mounted on the cylindrical mounting head and positioned directly opposite the machining rear hole of the rear hole positioning lower block.

[0009] The tool reset mechanism includes a reset fixed plate, a reset movable plate, and a reset spring. The reset fixed plate is fixedly located below the frame plate. The reset movable plate is movably located between the frame plate and the reset fixed plate and is located below the bottom of the tool mounting block of the movable tool assembly. The reset spring is located between the reset fixed plate and the reset movable plate.

[0010] When the tool mounting block of the movable tool assembly is subjected to force and moves downward, it can push the reset moving plate downward, causing the reset spring of the tool reset mechanism to compress and store force. At the same time, the rear hole tool moves downward and inserts into the machining rear hole of the rear hole positioning lower block. When the reset spring extends and resets, it can push the reset moving plate upward, causing the tool mounting block and the rear hole tool to move upward until they are reset.

[0011] In the optimized version, the present invention also includes a front-end processing mechanism located near the other side of the front hole processing mechanism. The front-end processing mechanism includes a vertical pressure plate, a front-end movable block, a front-end cutter, a front-end positioning head, and a reset cylinder. The vertical pressure plate is a vertically arranged plate-shaped structure located below the rear of the lower pressure plate. The lower rear end of the vertical pressure plate gradually narrows towards the lower front end, giving the lower part of the vertical pressure plate an inclined pressure surface. The front-end movable block is longitudinally movable above the frame plate, and its rear end has an inclined guide surface that matches the inclined pressure surface of the vertical pressure plate. The front-end cutter is a plate-shaped structure obliquely mounted on the bottom of the front end of the front-end movable block, with its cutting edge located above the front of the frame plate. The front-end positioning head is a longitudinally arranged columnar structure located below the front-end cutter at the upper front of the frame plate. The reset cylinder is located near the rear end of the front-end movable block on the frame plate, with its output shaft facing the front-end movable block.

[0012] When the lower pressure plate moves downward under force, the inclined pressure surface of the vertical pressure plate pushes the inclined guide surface of the front movable block, causing the front movable block to drive the front cutter to move backward; when the output shaft of the reset cylinder extends, it can push the front movable block forward until the front cutter is reset.

[0013] Furthermore, the front-end processing mechanism also includes a movable block cover that covers the front movable block. The front movable block has two plugs symmetrically arranged on both sides. The movable block cover has an elongated slot corresponding to the plug of the front movable block. The plug of the front movable block can move along the elongated slot of the movable block cover.

[0014] In the optimized solution of this invention, two longitudinal support rods are symmetrically arranged at the lower front of the frame plate on the machine frame. The longitudinal support rods are equipped with a station moving mechanism and a pipe clamping mechanism. The station moving mechanism includes a moving base plate, a transverse guide rod, a transverse screw, a transverse moving block, a transverse drive motor, and a longitudinal drive cylinder.

[0015] The transverse screw and transverse guide rod are arranged sequentially and close to each other on the movable base plate. One end of the transverse moving block is threadedly connected to the transverse screw, and the other end is movably placed on the transverse guide rod. The output shaft of the transverse drive motor is coaxially connected to the transverse screw and can drive the transverse screw to rotate so that the transverse moving block moves along the transverse guide rod. The movable base plate is movably placed on two longitudinal support rods.

[0016] The longitudinal drive cylinder is located below the movable base plate and is fixedly connected to the movable base plate. The end of its output shaft is fixedly connected to the frame plate of the machine frame. The longitudinal drive cylinder can drive the movable base plate to move along the longitudinal support rod, and make the transverse guide rod, transverse screw, transverse moving block and transverse drive motor move synchronously along the longitudinal support rod.

[0017] The pipe clamping mechanism includes a chuck and a chuck cylinder. The chuck consists of two clamping plates that are movably hinged in the middle. The chuck cylinder is located in front of the chuck, and its output shaft faces the chuck. When the output shaft of the chuck cylinder extends, it can bring the rear ends of the two clamping plates closer to each other. The pipe clamping mechanism can be driven by the longitudinal movement drive cylinder to move longitudinally along the longitudinal support rod, or it can be driven by the transverse movement drive motor to move laterally along the transverse guide rod.

[0018] Furthermore, the longitudinal support rod is connected to the frame plate of the machine frame via a longitudinal guide rod. The longitudinal guide rod is fixedly connected to the frame plate, and a longitudinal screw is threaded to its front end. One end of the longitudinal support rod is connected to the longitudinal guide rod, and the other end is threaded to the longitudinal screw. Rotating the longitudinal screw can cause the longitudinal support rod to move back and forth along the longitudinal guide rod, thereby adjusting the distance between the pipe clamping mechanism and the frame plate of the machine frame.

[0019] In the optimized solution, the present invention provides a feeding mechanism on the side of the frame plate away from the rear hole processing mechanism. The feeding mechanism includes a front feeding guide rod, a rear feeding guide rod, and a feeding slide plate. The front feeding guide rod and the rear feeding guide rod are symmetrically arranged to form a feeding guide frame.

[0020] The end of the front feeding guide rod is located at the upper front of the frame plate near the station moving mechanism. Its end is located inside the feeding guide and is equipped with a longitudinal telescopic rod. The outer wall of the longitudinal telescopic rod has a pipe adjustment groove.

[0021] The end of the rear feed guide rod is close to the frame plate, and its end is movably hinged to the feed valve plate inside the feed guide. The top of the feed valve plate can be driven by a valve plate cylinder to open or close the end of the feed guide.

[0022] The feeding slide plate is laterally movable and has a longitudinal slot at its top. One end of the feeding slide plate is located below the end of the feeding guide and the other end is located on the frame plate. The feeding slide plate can be pushed by a slide plate cylinder to move laterally between the feeding guide and the frame plate.

[0023] This invention has the following outstanding substantive features and significant progress:

[0024] 1. This invention achieves multi-hole processing of pipe fittings through a front hole processing mechanism and a rear hole processing mechanism. Furthermore, the front-end processing mechanism sets longitudinal smoothing grooves on the openings of the pipe fittings to prevent bolt slippage during bolt connection of the finished pipe fittings. This invention further utilizes the cooperation of a station moving mechanism and a pipe fitting clamping mechanism to enable the pipe fitting clamping mechanism to continuously move the pipe fitting to multiple processing stations, achieving automated control during the multi-hole processing of pipe fittings; and further utilizes a feeding mechanism to achieve continuous, automatic, and positioned feeding of the pipe fittings.

[0025] 2. The present invention has a high degree of automation control. After the pipes enter the feeding mechanism, no manual operation is required. The movement of the corresponding parts can be realized by adjusting each cylinder, and the rotation of the corresponding parts can be realized by adjusting each motor, thereby achieving the purpose of displacement control. It has the characteristics of fast and efficient processing, as well as high degree of automation control, strong controllability, and excellent and stable processing quality.

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] Example

[0035] refer to Figures 1 to 9 A multi-hole pipe processing equipment includes a frame 1, a feeding mechanism, a station moving mechanism, a pipe clamping mechanism, a front processing mechanism, a front hole processing mechanism, and a rear hole processing mechanism.

[0036] The frame 1 includes a frame plate 11, vertical guide columns 12 and a lower pressure plate 13. Two vertical guide columns 12 are symmetrically arranged on the frame plate 11 of the frame 1. The lower pressure plate 13 is located above the frame plate 11, and its two ends are movably sleeved on the two vertical guide columns 12. The lower pressure plate 13 can move up and down above the frame plate 11 along the vertical guide columns 12.

[0037] like Figure 6 and Figure 7 The front-end processing mechanism includes a vertical pressure plate 7, a front-end movable block 71, a front-end cutter 72, a front-end positioning head 73, and a reset cylinder 74. The vertical pressure plate 7 is a vertically arranged plate-shaped structure located below the rear of the lower pressure plate 13. The lower rear end of the vertical pressure plate 7 gradually narrows towards the lower front end, giving the lower part of the vertical pressure plate 7 an inclined pressure surface 70. The front-end movable block 71 is longitudinally movable above the frame plate 11, and its rear end has an inclined guide surface 710 that matches the inclined pressure surface 70 of the vertical pressure plate 7. The front-end cutter 72 is a plate-shaped structure obliquely mounted on the bottom of the front end of the front-end movable block 71, with its cutting edge located above the front of the frame plate 11. The front-end positioning head 73 is a longitudinally arranged columnar structure located below the front-end cutter 72 above the front of the frame plate 11. The reset cylinder 74 is located near the rear end of the front-end movable block 71 on the frame plate 11, and its output shaft is positioned directly opposite the front-end movable block 71.

[0038] When the lower pressure plate 13 is subjected to force and moves downward, the inclined pressure surface 70 of the vertical pressure plate 7 pushes the inclined guide surface 710 of the front movable block 71, causing the front movable block 71 to drive the front cutter 72 to move backward; when the output shaft of the reset cylinder 74 extends, it can push the front movable block 71 forward until the front cutter 72 is reset.

[0039] like Figure 8 The front hole machining mechanism includes a front hole cutter 2, a front hole positioning head 21, and a movable block cover 75. The front hole cutter 2 and the front hole positioning head 21 are arranged vertically and vertically. The front hole cutter 2 is a vertically arranged cylindrical structure located at the lower front of the lower pressure plate 13. The front hole positioning head 21 is a longitudinally arranged cylindrical structure located at the upper front of the frame plate 11. The front hole positioning head 21 has a machining front hole 211 that is directly opposite the front hole cutter 2. When the lower pressure plate 13 is subjected to force and moves downward, the front hole cutter 2 can be inserted into the machining front hole 211 of the front hole positioning head 21.

[0040] The movable block cover 75 covers the front movable block 71. The front movable block 71 has two symmetrically arranged plugs 711 on both sides. The movable block cover 75 has an elongated slot 751 corresponding to the plugs 711 of the front movable block 71. The plugs 711 of the front movable block 71 can move along the elongated slot 751 of the movable block cover 75.

[0041] like Figure 9 The rear hole machining mechanism includes a rear hole positioning upper block 3, a rear hole positioning lower block 4, a movable tool assembly, and a tool reset mechanism. The rear hole positioning upper block 3 is located at the lower front of the lower pressure plate 13, and its bottom has a longitudinally arranged arc-shaped positioning upper groove 31.

[0042] The lower positioning block 4 is located at the front of the upper part of the frame plate 11. Its top has a longitudinally arranged arc-shaped positioning groove 41. The upper positioning groove 31 and the lower positioning groove 41 are arranged vertically and vertically respectively. The lower positioning groove 41 has a vertically arranged machining hole 42.

[0043] The movable tool assembly includes a tool mounting block 51, a cylindrical mounting head 52, and a rear hole tool 5. The tool mounting block 51 is vertically movably positioned above the frame plate 11 at the rear of the rear hole positioning lower block 4, with its bottom movably passing through the frame plate 11. The cylindrical mounting head 52 is longitudinally positioned at the front of the tool mounting block 51. The rear hole tool 5 is a vertically positioned cylindrical structure, which is mounted on the cylindrical mounting head 52 and positioned directly opposite the machining rear hole 42 of the rear hole positioning lower block 4.

[0044] The tool reset mechanism includes a reset fixed plate 6, a reset movable plate 61, and a reset spring 62. The reset fixed plate 6 is fixedly disposed below the frame plate 11. The reset movable plate 61 is movably disposed between the frame plate 11 and the reset fixed plate 6, and is located below the bottom of the tool mounting block 51 of the movable tool assembly. The reset spring 62 is disposed between the reset fixed plate 6 and the reset movable plate 61.

[0045] When the tool mounting block 51 of the movable tool assembly is subjected to force and moves downward, it can push the reset moving plate 61 to move downward, causing the reset spring 62 of the tool reset mechanism to compress and store force. At the same time, the rear hole tool 5 moves downward and inserts into the machining rear hole 42 of the rear hole positioning lower block 4. When the reset spring 62 extends and resets, it can push the reset moving plate 61 to move upward, causing the tool mounting block 51 and the rear hole tool 5 to move upward until they are reset.

[0046] Two longitudinal support rods 14 are symmetrically arranged at the lower front of the frame plate 11 on the frame 1. The station moving mechanism and the pipe clamping mechanism are located on the longitudinal support rods 14.

[0047] like Figure 5 The workstation moving mechanism includes a moving base plate 8, a transverse guide rod 81, a transverse screw 82, a transverse moving block 83, a transverse drive motor 84, and a longitudinal drive cylinder 85.

[0048] The transverse screw 82 and the transverse guide rod 81 are arranged close to each other on the movable base plate 8. One end of the transverse moving block 83 is threadedly connected to the transverse screw 82, and the other end is movably placed on the transverse guide rod 81. The output shaft of the transverse drive motor 84 is coaxially connected to the transverse screw 82 and can drive the transverse screw 82 to rotate, so that the transverse moving block 83 moves along the transverse guide rod 81. The movable base plate 8 is movably placed on two longitudinal support rods 14.

[0049] The longitudinal drive cylinder 85 is located below the movable base plate 8 and is fixedly connected to the movable base plate 8. The end of its output shaft is fixedly connected to the frame plate 11 of the frame 1. The longitudinal drive cylinder 85 can drive the movable base plate 8 to move along the longitudinal support rod 14, so that the transverse guide rod 81, transverse screw 82, transverse moving block 83, and transverse drive motor 84 move synchronously along the longitudinal support rod 14.

[0050] The pipe clamping mechanism includes a chuck 86 and a chuck cylinder 87. The chuck 86 consists of two clamping plates 861 that are movably hinged in the middle. The chuck cylinder 87 is located in front of the chuck 86, and its output shaft faces the chuck 86. When the output shaft of the chuck cylinder 87 extends, it can bring the rear ends of the two clamping plates 861 closer to each other. The pipe clamping mechanism can be driven by the longitudinal movement drive cylinder 85 to move longitudinally along the longitudinal support rod 14, and can also be driven by the transverse movement drive motor 84 to move laterally along the transverse guide rod 81.

[0051] The longitudinal support rod 14 is connected to the frame plate 11 of the frame 1 via the longitudinal guide rod 15. The longitudinal guide rod 15 is fixedly connected to the frame plate 11, and its front end is threaded with a longitudinal screw 16. One end of the longitudinal support rod 14 is connected to the longitudinal guide rod 15, and the other end is threaded to the longitudinal screw 16. Rotating the longitudinal screw 16 can cause the longitudinal support rod 14 to move back and forth along the longitudinal guide rod 15, thereby adjusting the distance between the pipe clamping mechanism and the frame plate 11 of the frame 1.

[0052] like Figure 1 and Figure 2 The front-end processing mechanism, the front hole processing mechanism, and the rear hole processing mechanism are arranged alternately in sequence. A feeding mechanism is provided near the front-end processing mechanism on the side of the frame plate 11 on the frame 1. The feeding mechanism includes a front feeding guide rod 91, a rear feeding guide rod 92, and a feeding slide plate 9. The front feeding guide rod 91 and the rear feeding guide rod 92 are symmetrically arranged to form a feeding guide frame.

[0053] The end of the front feed guide rod 91 is located at the upper front of the frame plate 11 near the station moving mechanism. Its end is movably equipped with a longitudinal telescopic rod 911 within the feed guide frame. The outer wall of the longitudinal telescopic rod 911 has a pipe adjustment groove 912, such as... Figure 3 .

[0054] The end of the rear feed guide rod 92 is close to the frame plate 11, and its end is hinged to a feed valve plate 921 within the feed guide frame. The top of the feed valve plate 921 can be driven by a valve plate cylinder 922 to open or close the end of the feed guide frame. Figure 4 The feeding slide plate 9 is laterally movable and has a longitudinal slot 90 on its top. One end of the feeding slide plate 9 is located below the end of the feeding guide and the other end is located on the frame plate 11. The feeding slide plate 9 can be pushed by a slide plate cylinder 901 to move laterally between the feeding guide and the frame plate 11.

[0055] The working principle of this invention is as follows:

[0056] The pipe fitting 101 enters through the feeding guide of the feeding mechanism. The feeding valve plate 921 prevents the pipe fitting 101 from stopping at the end of the feeding guide. A longitudinal telescopic rod 911 is inserted into the end of the pipe fitting 101, and the pipe fitting 101 is adjusted by matching the pre-set groove on the pipe wall at the end of the pipe fitting 101 with the pipe fitting adjustment groove 912, ensuring that all pipe fittings 101 enter the subsequent process in the same position. Afterwards, the feeding valve plate 921 opens, allowing the pipe fitting 101 to fall into the longitudinal slot 90 of the feeding slide plate 9. The slide plate cylinder 901 pushes the feeding slide plate 9, sending the pipe fitting 101 to the vicinity of the front-end processing mechanism.

[0057] Subsequently, the station moving mechanism drives the pipe clamping mechanism to move longitudinally via the longitudinal drive cylinder 85 and to move laterally via the transverse drive motor 84, so that the pipe clamping mechanism moves sequentially to the four stations directly in front of the feeding slide plate 9, the front processing mechanism, the front hole processing mechanism, and the rear hole processing mechanism.

[0058] First, at the feeding slide plate 9 station, the longitudinal drive cylinder 85 drives the pipe clamping mechanism to move backward, while the open chuck 86 clamps the pipe 101 at the feeding slide plate 9 station. Then, the chuck cylinder 87 keeps pressing against the chuck 86 to clamp the pipe 101. After that, the longitudinal drive cylinder 85 drives the pipe clamping mechanism to move forward, and the pipe 101 is clamped on the feeding slide plate 9.

[0059] Then, the transverse drive motor 84 drives the pipe clamping mechanism to move laterally to the front processing mechanism station. The longitudinal drive cylinder 85 first drives the pipe clamping mechanism to move backward, placing the end of the pipe 101 onto the front positioning head 73 of the front processing mechanism. The lower pressure plate 13 is driven downward by an external pressure device such as a punch press or hydraulic press, causing the inclined pressure surface 70 of the vertical pressure plate 7 to push the inclined guide surface 710 of the front movable block 71. The front movable block 71 drives the front cutting tool 72 to move backward, machining a longitudinal smoothing groove 1011 on the end of the pipe 101. Afterward, the lower pressure plate 13 moves upward under force, and the longitudinal drive cylinder 85 drives the pipe clamping mechanism to move forward, removing the pipe 101 from the front positioning head 73. Figure 6 and Figure 7 .

[0060] Then, the transverse drive motor 84 drives the pipe clamping mechanism to move laterally to the front hole machining mechanism position. The longitudinal drive cylinder 85 first drives the pipe clamping mechanism to move backward, placing the end of the pipe 101 onto the front hole positioning head 21 of the front hole machining mechanism. The lower pressure plate 13 is pressed down, and the front hole tool 2 is pressed into the pipe 101 until it is inserted into the machining front hole 211 on the front hole positioning head 21. The front hole 1012 is machined in the longitudinal smoothing groove 1011 on the end of the pipe 101. Afterward, the lower pressure plate 13 is moved upward, and the longitudinal drive cylinder 85 drives the pipe clamping mechanism to move forward, removing the pipe 101 from the front hole positioning head 21. Figure 8 .

[0061] Finally, the transverse drive motor 84 drives the pipe clamping mechanism to move laterally to the position of the rear hole machining mechanism. The longitudinal drive cylinder 85 first drives the pipe clamping mechanism to move backward, placing the end of the pipe 101 onto the cylindrical mounting head 52 of the rear hole machining mechanism. The lower pressure plate 13 is pressed down against the tool mounting block 51, causing the rear hole tool 5 to move downward and press against the end of the pipe 101. After the rear hole tool 5 passes through the end of the pipe 101, it is inserted into the machining rear hole 42 of the rear hole positioning lower block 4, machining the rear hole 1013 below the front hole 1012 on the end of the pipe 101. Afterward, the lower pressure plate 13 is moved upward, and the longitudinal drive cylinder 85 drives the pipe clamping mechanism to move forward, removing the pipe 101 from the cylindrical mounting head 52. Figure 9 The output shaft of the chuck cylinder 87 of the pipe clamping mechanism leaves the chuck 86, causing the chuck 86 to release the pipe 101, thus completing the machining.
